This invention relates to an anvil for fuel hoggers or for a machine forgrinding up slabs and all kinds of scraps, the general object of theinvention being to make the anvil in such a manner that the cuttingplate or blade can be readily and quickly adjusted to take up wear, sothat the anvil will last for along time and when it is necessary ordesired the cutting blade can be removed and replaced by a newone withbut little effort, and as the blade is a comparatively small one, and itis simply necessary to replace the blade and not the entire anvil, thecost of replacement is very small.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described and claimed, illustrated in the accompanyingdrawings, and specifically pointed out in the appended claim.

In describing the invention in detail, refer ence will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation with the parts broken away and showing a hogging or woodgrinding machine to which the invention is applied. a

1,-the wood grinding machine is used for grindmg slabs and all kinds ofscrap wood, generally at saw mills, and this produces what is called hogfuel and is generally referred to as a fuel hogger, andcomprises thehousing A into which the wood is introduced through the member B and inwhich housing is the rotary cutting member shown generally at C whichcooperate with a pair of anvils D, these anvils being-carried by theremovable sections E of the housing, which are hingedly connected, tothe main part of the'housing at F. All of these parts are of well known:con struction-and my invention relates to the anvils D. i

Heretofore these anvils have been formed of chilled steel so that theywear quickly and they are each formed of a single piece so that whenthey do wear out, the entire plate or piece is promptly removed andsubstituted by a new one.

In carrying out my invention, I form each anvil of a plate 1 having arecess 2 in one face thereof, which extends from one end of the plate tothe other at a point Well below the top of the plate, through the loweredge of the plate, and the lower wall of the recess is beveled as shownat 2 to form a seat for the blade 3 which is in the shape of arectangular bar and of such a width that the upper edge of said bar willextend into the deeper part of the recess so that said upper edge can beengaged by the enlarged parts lef the rods 5 located in the verticalgrooves or bores 6 in the plate 1 and arranged inwardly of the res cess2 and having portions incommunication with-said recess as shown in Fig.6.

The upper end of each rod '5 isformed with a threaded part 7 forengaging threaded openings 8 in the plate. Each opening forms acontinuation of the bore 6 and each rod 5 is formed with a head 9 whichis located in an opening 10 formed in the top of the plate. A strip 11is fastened by the screws 12to the top edge of the plate, and cover theopenings 10, and the heads 9 of the rods 5. A clamping plate 13, isconnectedwith the plate 1 by the bolts 14, the major portion of theclamp ing plate resting in the recess 2 and said plate 13 is providedwith a clamping part 13 for blade can be removed and a new one clampingthe blade 3 against the seat 2' when the bolts 14 are tightened.

The outer face of the plate 13 is of arcshape in cross section as shown.The inner face of the plate 13 is substantially fiat and it is formedwith the small recesses 15 for receiving portions of the enlargements 4and the threaded portions 7 as clearly shown in Fig. 9.

The heads of the bolts 14 fit in recesses 16 formed in the outer face ofthe plate 13, and large circular recesses 17 are formed on the outerface of the plate 13 for receiving the nuts 18 on the bolts 19 whichconnect the'anvil to the supporting member 20 of the machine, the headsof the bolts 19 fitting in the substantially bayonet-like slots 21 insaid member 20 as shown in Fig. 10. Thus by raising the anvil, the headsof the bolts 19 will be free of the small portions of the slots 21 sothat they can be passed through the large parts of the slots to free theanvil from the supporting member, but when the heads of the bolts 19 arein the small parts of the slots 21 the anvil will be securely locked tothe member 20. f

From the foregoing, it will be seen that by opening either one ofthemovable sections E, the heads of the bolts 9 are exposed so that thebolts or rods 5 can be turned to cause the enlargements 4 to press uponthe upper edge ofthe blade 3 afterthe bolts 14 are loosened to adjustthe blade downwardly so as to take up wear of the exposed edge of theblade;

The bolts 14 are then tightened to cause the clamping plate 13 to clampthe blade in adjusted position. When the wear of the blade is such as tonecessitate its replacement by a new blade this can be easily andquickly done by removing the clamping plate 13 or loosening the bolts 14thereof so that tho ollod su stituted therefor.

Then the bolts 14 are tightened to cause the plate 13 to clamp a newblade in position.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes'may be" with the lower edge of theplate beveled to engage the blade to hold the blade upon its seat, aplurality of bolts threaded in the upper part of the first plate andhaving their lower ends engaging the upper edge of the blade wherebyturning movement of the bolts will adjust the blade downwardly, meansfor detachably connecting the anvil to its supporting member, such meanscomprising headed bolts passing through the anvil member, and saidsupporting member having bayonet slots therein for receiving the headsofthe bolts.

In testimony whereof I affix my signature.

provided that such changes fall within the scope of the appended claim.

Having thus described my invention; what I claim as new is A11 anvil fora fuel hogger comprising a plate-like member having a recess in one facethereof which extends from one end of the plate to the other with thelower wall of the I recess sloping downwardly and outwardly to form aseat, a blade resting on the seat, a clamping platevbolted to thefirst-mentioned plate and having a portion seated in the recess
